Fortress Mentality

Fortress mentality refers to a defensive attitude where individuals, organizations, or countries isolate themselves to protect their resources, interests, or values. It involves creating barriers—physical, social, or ideological—to ward off external threats or influences. This mindset often leads to resistance against change, collaboration, or outside ideas, driven by fear of vulnerability or loss. While it can provide a sense of security, it may also result in stagnation or missed opportunities for growth and innovation, as openness and adaptability are sacrificed in favor of insularity.
